AI Technical Summary

Benefits of technology

Reduces labor costs and skill requirements by enabling the construction of curved drywall ceilings with a range of curvatures using adjustable grid tees, maintaining stability and allowing for conventional suspension methods.

Problems solved by technology

This variety makes it impractical for manufacturers to produce and inventory an array of grid tees that could correspond to the possible arched ceilings that might be specified.
On site fabrication of framework for a curved drywall ceiling can require a high level of skill and extensive man hours making such ceiling construction relatively expensive.

second embodiment

[0027]FIGS. 8-10 illustrate the invention in which a curvable tee 40 has segments 41. Stems 42 of the segments 41 are severed from one another while flanges 43 of the segments 41 remain longitudinally continuous from segment-to-segment. The tee 40 is made from a single sheet metal blank 44, a short length of which is illustrated in FIG. 9. The blank 44 is formed with cross tee slots 45 and hanger holes 50. The blank 44 is folded 180 degrees on itself at a longitudinal centerline 46 to establish a double layer segment stem 42. The blank 44 is bent 90 degrees along lines 47 passing through longitudinally oriented slots 48 to create the oppositely extending flanges 43. Arcuate slots 49 connect between the longitudinal slots 48 and rectangular holes 51 along the centerline 46. The holes 51 separate adjacent segments 41.

[0028]The flange area in the blank 44 can be scored or notched transversely to the length of the blank 44 at lines 52 to assure that the tee 40 will bend along such lines...

third embodiment

[0029]FIGS. 11-13 illustrate a curvable tee 60 in the invention. The tee 60 has segments 61 each with a stem 62 and flanges 63. The segments 61 are unitary with one another. The tee 60, additionally, includes a flange face strip 64. FIG. 13 illustrates a fractional length of a blank 66 stamped from a strip of sheet metal from which the stem 62 and flanges 63 are formed. The blank 66 includes hanger wire receiving holes 67 and cross tee connector slots 68. The blank 66 is folded on itself at a centerline 69 to form the double layer segment stems 62 and bent at 90 degrees at the broken lines 71 to form opposed segmented flanges 63.

[0030]The flange face strip 64 extends continuously longitudinally along the full length of the tee 60. As shown in FIG. 12, the longitudinal margins of the face strip 64 are folded around distal edges of the flanges 63 in the manner of a hem to hold the strip on the flanges while allowing relative local slip between a segment 61 and the strip while maintain...

Abstract

A curvable grid tee for suspending drywall capable of being configured vertically into convex or concave shapes comprising a series of identical web segments joined end-to-end, the segments being formed of sheet metal into a tee shaped cross section, the sheet metal of a segment being folded such that each segment has a vertical double layer stem with the stem layers joined at a common fold at upper edges thereof, the sheet metal at lower edges of each layer of the stem being bent outwardly to form a flange, a junction between adjacent segments permitting such adjacent segments to be angularly displaced relative to one another in a vertical plane such that the flanges are capable of supporting a drywall panel in a curved plane.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to grid members of adjustable curvature for constructing curved drywall ceilings.PRIOR ART[0002]Architects, interior designers, building owners and / or tenants from time to time specify curved ceilings for obtaining a desired look that distinguishes a room or space from the utilitarian appearance of a flat ceiling. The radii of curvature ordinarily varies from site to site and can even vary at a particular site. This variety makes it impractical for manufacturers to produce and inventory an array of grid tees that could correspond to the possible arched ceilings that might be specified.[0003]On site fabrication of framework for a curved drywall ceiling can require a high level of skill and extensive man hours making such ceiling construction relatively expensive.[0004]There is a need for manufactured grid members capable of reducing labor costs and required skill and that can be used for a full range of curvatures.SUMMARY OF THE ...
